As a practical approach to the Introduction to Ecology and Environmental Sciences course, the students are provided with different digital fabrication workshops.

We strongly believe in Fab Academy's hands-on learning philosophy and aim to promote interest in digital fabrication among college students.

Period: Winter Semester 2021 / 22
Lecturer: Jefferson Josué Sandoval Betanco

In the context of the global situation, these sessions were made in a hybrid way.

These digital manufacturing practices were composed of three sessions:

1. Introduction to Arduino
   
   Students get familiar with the basic theory: What is a microcontroller? What is Arduino (both boards and software)? What is the application?
   
   As examples for applications of digital fabrication, different FabAcademy final projects were shown. The final project, which is the Irrigation system, was explained.
   
   We made our first practice with an Arduino board: turning on and off, then blinking the built-in LED in different ways. Offline students were provided with an Arduino UNO board, Online students made it in TinkerCAD.

2. Introduction to Inputs and Outputs
   
   This session had to be split into two days (first day for digital practice, second day for physical circuits).
   
   Day 1:
   For this practical session both offline and online students were guided to make and simulate in TinkerCAD circuits and codes for:
   a. Fading LEDs.
   b. Ultrasonic distance sensor and LEDs.
   c. DC motor test.
   
   Day 2:
   The offline students were provided with electronics kits to replicate in reality the previous digital practice. An extra practice including a Capacitive soil moisture sensor was carried out. In the end, the students worked on making the circuit and code for the irrigation system.

3. Introduction to 3D model and printing
   
   At the beginning, the idea for practice was to make a case for the system; this idea was reevaluated and modified to make keychains due to it's easier to ensure and evaluate the activity of each student, also a case is something that can be just downloaded from the internet and we rather them to make something for themselves (or a relative).
   
   Note: 3D printed parts are not shared here for privacy but have of course been evaluated and included in a final report.

Students were asked to form groups of a maximum of 6 people, including at least 2 who could attend the sessions in person.
